GRADER.

SPECIFICATION forming part of Letters Patent No. 309,548, dated December23, 1884-,

ApplioaiionliledMart-h5,1584. (No model.)

To ctZZ whom it may concern:

Be it known that I, HENRY HILD, a citizen of the United States, residingat Britt, in the county of Hancock and State oflowa, have invented anImprovement in Graders, of which the following is a specification.

This invention relates to that class of graders which are used to makeroads by moving the earth from the ditch at each side of the road to thecenter thereof to raise the same above the common level, or to loadwagons.

The object of my invention is to plow up the earth, and to carry thesame the required distance to one side of the furrow, or load it into awagon at one and the same operation.

To this end my invention consists in the construction and combination ofparts, here iii-after described and claimed, reference being had to theaccompanying drawings in whieh- Figure l is a side elevation, Fig. 2 isa plan view, and Fig. 5 is a .rear elevation,of my improved grader.

A represents the plow, secured by a vertical post, a, to a longitudinalbeam of the main frame 13 of the machine. The frame B is supported onthree wheels, D, E, and F, The

wheel 1) is fixed to run in the furrow by means of avertically-adjustable bifurcated post, (7, in the lower end of which thewheel is journaled. The upper end of this post is pivoted to a lever, e,which is in turn pivoted to the frame B, and the middle of the postpasses through the frame. By means of lever e the post (I and wheel 1)may be pressed upen, so as to raise the frame B and take the plow out ofthe ground.

0 is an are attached to the frame, and provided with pin-holes, intowhich a pin may be inserted above or below lever 0, either to hold thewheel up from the ground, so that the plow may be guidedas to the depthof its furrow without the assistance of wheel I); or the wheel may beset just as low as the plow to assist the latter in supporting frame B;or the wheel may be thrust low down to support the frame and carry theplow above ground. The wheel D is mounted in a swinging yoke, ltwhich ispivoted at its rear end to the frame B, and at its forward end to alever, b, which is fulcrumed at c on a stud erected on frame B. Thiswheel D is to run on top of the ground ahead of the plow, and by raisingor lowering it the depth of the furrow may be gaged. The lover I) isheld at any desired elevation by a brace, 0, having pin-holes in it, anda pin adapted to pass through said holes and through the lever b.

E is a caster-wheel supporting the forward part of the frame.

F is a large drive-wheel, made rough on its circumference to engage theground to insure the wheels turning when the machine is hauled along.This wheel F is journaled in a yoke, f, which is pivoted to the frame Batf, concentric with a shaft, G. The drive-wheel F is provided with acircle of gear-teeth, g. which engage a pinion, G, on shaft G.

H is a beveled gear-wheel secured 011 shaft G, engaging another beveledwheel, 7.2, 011 shaft h.

I is an endless apron ol'slats secured together by hingejoints, ashereinafter described, to travel as a belt around the cylinders 2' t".The cylinder 2" is carried very close to the ground, and close to themold-board of the plow, to receive the earth turned up thereby upon theapron. Thelower end of the frame I, supporting the cylinders i 1 whichcarry the apron,

i is supported by hangers i,'depending from the frame 13. The middleportion of the frame I rests upon the main frame B, and it may bevertieall y adjustable to set the roller t" high or low.

hen the grader is used for grading only, the frame I will lie at a veryslight inclination to a horizontal plane, and will be made to extendbeyond the main body of the grader as far to one side as may be desired.

When the grader is used for loading wagons, the frame 1 will besufficiently elevated at its outer end to carry cylinder i over thewagon alongside, thus enabling the apron I to continually dump its loadinto the wagon. The frame I is thus a lateral extension of the mainframe 13. The apron is rotated by means of achain, J, running from arag-wheel on cylinder t to a rag-wheel, K, 011 the shaft h of a beveledgear, it, which on gages another beveled gear, H, on shaft G, carried bypinion G, thus engaging with the drive-wheel F. \iVhen the machineadvances, the plow turns a furrow of earth onto the apron, which dumpsit to one side, or into a wagon hauled alongside, as desired.

Zis a cross-beam secured to the end of the team-pole M, for the doublepurpose of securing the forward team in proper line of draft at m, andto haul the plow by means of the connecting rod or chain N. The firstteam of three horses is secured to a draft-rod, n, by means of peculiarequalizing-whiiiietrecs.

Ois the double-tree made in duplicate parts, one above the other,admitting the equalingbars 0 between its parts. The equaling-bars 0 arepivoted one-third their length from their outer ends to the double-tree.On the outer end of each bar 0 is hunga single-tree or whiffletree, P,for one horse each. On the inner ends of both bars 0 is hung anotherwhiffletree, 1?, for one horse to pull against thetwo outside horses. Bythis means the strain is more direct than by the old style of threehorsegear. A forward team may be secured by the same style of gear to theframe at m. The frame B is raised or lowered relative to the axle ofwheel F by means of a rope or chain, R, wound upon an axle, 0', bycranks S, the rope passing around a pulley, T, on

the frame B, and under another pulley, t, on

an arm of said frame, thence upward to the yoke f, to which it issecured. By turning cranks S one way therope R will be wound onto shaft1, and will draw the frame B at pulley t up toward yokef, and viceversa, the frame B swinging upon the other wheels, D D E, and upon thepivotf of yokef. Either of the cranks S may be pushed through thecranklever into the frame B, to retain the crank at any desired point,and thus hold the frame elevated.

V is a seat for a driver. This seat is supported over the apron on rodsextending to the frame B. It is thought that earth may by means of thisdevice be very much more rapidly moved away from the plow which loosensit than by any method of scraping said loosened earth along the ground,inasmuch as A the friction of my carrier apron, revolving upon smalljournaled cylinders, is less than the friction of any scraper carryingthe same load over rough ground; also, this means of 'may have gotbetween the belt may be free to drop out.

\Vhat I claim as my invention, and wish to secure by Letters Patent, is-

1. The combination, with the earth-moving device, comprising the plow A,the beltI, and the driving mechanism described supported upon frame B,ofthe team-connecting rod 12, and the beam or poleM, secured to saidframe B, the cross-beam Z, secured to pole M, the team-hitch m,attachedto beam Z, and the stayrod N, connecting the end of said beam with theframe B, substantially as shown and described.

2. The combination, with a graderframe provided with a plow and meansfor carrying laterally therefrom the earth turned up thereby, of adrive-wheel hung in a vertically-adjustable yoke to said frame, a ropeor chain attached to said yoke and passing around pulleys on the frame,and means for winding said rope and securing it, whereby the frame maybe elevated relative to the yoke and held at the height desired, asspecified.

HENRY HILD.
